ちょっといろいろ面倒になったので、THINKLETに接続したらRaspiに動画をコピーするツールを作る。
経験的にはgvfsは不安定なところがあるので嫌い。前に検証したlibmtpでやりたい。
libmtpやってみる

libmtpやってみる -1- 2025年7月3日 08:00 LINKLETはMTPデバイスとして認識される。ちょっとこれをいじる必要が出てきたので、下調べ。MTPとか今更という気もするけど、しょうがないしょうがない。 Viewerをそのまま使うかな。環境はRaspiOS。使うのはPythonにしておくかな。 Python環境はこれでいいかな。 kinneko@pi3b:~ $ python --version Python 3.11.... 全体公開 kinneko

libmtpやってみる -2- 2025年7月4日 08:00 やっと動いたので、続き。 mtp-filetree: MTPデバイス上のファイルとフォルダをツリー形式で表示。 各ファイル/フォルダにはID (ハンドル) が付与される。 kinneko@pi3b:~ $ mtp-filetree Device 0 (VID=18d1 and PID=4ee1) is a Google Inc Nexus/Pixel (MTP). Attempting to connect device(s) Android... 全体公開 kinneko
実装は、都合によりPythonでやる必要があるので、GUIはpygameで。
libmtpの問題点としては、こんなところ。
・libmtpはファイルのmtime取得が弱いため、厳密な新着順は難しい（名前/サイズで擬似ソート）
・一部端末はmtp-thumbを返さない。その場合は初回クリック時のみ一時DLして縮小表示するなどが必要
・端末をロックすると転送が失敗する。画面ロック解除＋MTP選択を維持する。これは原則スリープのないTHINKLETなので問題ない。
・GVFSやFUSEを使う場合と比べ、一覧の初期取得が遅い機種がある。これは仕様に近い挙動なので修正できない。
勝手にマウントしちゃって競合するので、gvfsは止める。

バッチ内で「最終ファイル名」を予約して重複回避（完成ファイル/.part/予約の全てと衝突しない）
リネーム直前にも再確認して再解決（外部競合対策）

自動リトライは完全撤廃（各ファイル1回だけ）
失敗時の .part は削除せず残す（既に同名 .part があれば .part2 …で回避）

Hello from the pygame community. https://www.pygame.org/contribute.html
なんか、LINKLETからMTPで転送(libmtp使用)すると、大きめの動画ファイルとか末尾が転送失敗して壊れる感じがするのだけど、気のせいか？
ちょっと対策入れたら安定したようだ。
とりあえず、こんなもんかな。
